IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letter-l Patent and. making part of the lame.

We, ELISHA WALKER and JOSIAH J. PIATT, of

Indiana, have invented certain Improvements in Cultivators, of which the following is a specification.

Our invention relates to that class of cultivator-s which consists of a plow or plows swung between or behind two wheels.

Itrelates more particuiu'ly to the regulation and arrangement of the doubletree to be attached to the frame which carries the tongue, or to the tongue itself, so that the line of draught may be changed by changing the height of the single-trees, so that the draught may be made to come upon the breast of the horse, or upon his neck.

It has for its object to provide a double-tree, fastened by a king-bolt to the frame of a cultivator, and which said double-tree carriesthe plow-beams, the same being attached to it by a set of regulating-bars, which will hereinafter be more fully described, and which double-tree has also a chain or chains extending from the top to the bottom of the outside per-- pendicular regulating-bars, into which chains, at any link, may be hooked the single-trees, so that the draught maybe placed higher or lower, as desired, the object being to convert the invention from a walking-plow, that is to say, a plow in the working of which the plowman walks, into ariding-plow, upon which the plowman may ride; the weight of the plowman or driver hav ng atendency to tilt the tongue upward in all cultivators, when the tongue is firmly attached to the axle; the object of changing being to correct this tilting of the tongue, which raises with it the double-trees, and so changes the line of draught.

Descriptionof the Accompanying Drawings.

Figure 1 is a front view Figure 2 is a side view. Figure 3 is a detached part of fig. 1.

General Description. A is a double-tree, fastened to the tongue of a cultivator by a king-bolt, B. It may also be fastened to the frame of the cultivator. We fasten it to the tongue by bolting it to a transverse piece, 0, crossing the forked portion of the tongue D D. To this doubletree are fastened the stirrup-shaped iron frames E E, one at each end.

Pivoted to the double-tree, and to the bottoms of the said frames E E, are the regulating-bars F F, pierced with holes at the, proper distance apart, ranging up and down their length. The forward ends of any ordinary plow-beams being furnished with .metal jaws, are attached to these regulating-bars by-pi-ns through the holes. The beams may thus beattached at any desired height.

The outside perpendicular parts J J of the stirrupshaped iron frames are also pierced with holes, ranging up and down, into which holes the hooks Got the single-trees H may be hooked, so that the draught,

being from the single-trees, maybe placed at any desired height by placing the said single-trees at any of the holes along the parts J J. I

To further effect this object, the chains K K are fastened at the top, by a link, to the double-trees, at the joining of the said parts J J to the said double-trees. The bottom ends of the said chains K Kare then made fast, a'little slack being allowed to the parts J J near the bottom.

The books G may now be hooked into any of the links of the chains, and a more exact regulation effected. y

We claim, asour invention-- Tbe double-tree A, provided with the sti1rupshaped iron frames E E, with the pivoted regulating-bars F F and the chains K K, when combined and operating upon a cultivator, substantially as described and shown.
